Cooperative Great Plains Regional Project - reports, minutes, correspondence

clippings study

The James K. “Tex” Lewis Papers comprise research data, field notes, correspondence, publications, photographs, and teaching materials that document Lewis’s extensive range management research and instructional activities. The bulk of the materials pertain to Projects 216, 217, 239, and 421, long-running studies on forage production, grazing systems, livestock weight monitoring, and soil moisture dynamics conducted primarily at the Cottonwood Range Field Station, but also at Antelope Range Field Station, the Badlands, and other locations. The collection includes detailed observational and statistical data (e.g., point frame data, clip plot studies, Vegometer readings, and remote sensing imagery), climatological records, experimental livestock weights, soil analyses, and related environmental assessments. Boxes also include datasets used in simulation modeling (e.g., SPUR) and course materials for RANG, AS, and WL courses taught by Lewis.

Additional documentation reflects collaboration with national and regional entities such as the American Grassland Council, Society for Range Management, Great Plains Agricultural Council, and Bureau of Land Management. Also included are aerial photographs, GIS data, proposals, and internal reports, showcasing the depth and scientific rigor of Lewis’s methodology. Later series feature writings, technical guides, and training materials used in both academic and governmental range science settings.

This collection is a resource for understanding mid- to late-20th-century range science and ecosystem monitoring in the Great Plains. James K. Lewis’s work contributed significantly to innovations in grazing system design, range condition monitoring, and statistical modeling of range-livestock interactions. His leadership in integrating remote sensing, climatological data, and ecological classification methods helped shape contemporary range management practices. The materials are particularly valuable for researchers interested in the evolution of land use planning, sustainable grazing systems, and interdisciplinary range-livestock ecology. The inclusion of raw data and simulation outputs enhances the collection’s potential for longitudinal environmental and climatic studies.
